These Regulations are promulgated pursuant to Paragraph 3, Article 46 of the Telecommunications Act (hereinafter referred to as this “Act”).

The terms of these Regulations are defined as follows:
1. Field Strength: means radio wave strength with a unit of uV/m or dBuV/m tested by Standard Half-wave dipole Antenna at a height of 2m beyond the induction filed of antenna (a distance from one wavelength of antenna at least).
2. Ground Wave: Propagation of radio wave can be briefly classified as directed wave, reflected wave, refracted wave, diffracted wave, surface wave and scattered wave, where radio wave propagating along the surface of the earth is called Surface Wave and referred to as Ground Wave. Radio wave propagating from the reflection of the ionosphere is called Sky Wave. Directed Wave, Surface Reflected Wave and Ground Wave are jointly called On-ground Wave.
3. Relay Station: means station that doesn’t have the equipment to produce a program and uses a repeatered system to receive programs from main station as well as broadcasts them.
4. Shared Metal Tower: a tower of metal construction on which radio transmission antennas of two or more radio and/or television stations are installed.

Radio and TV Broadcast Station (hereinafter referred to as station) broadcasts audio, video and information with radio wave on the ground to provide the public listening in and watching. Reviews of engineering technique for the establishment of station, management of engineering personnel, engineering evaluation, equipment of station, the engineering technical regulations and equipment maintenance as well as supervision of radio wave for frequency, call sign and electric power used by station shall be stipulated by these regulations.

The competent authority of this rule is National Communications Commission.
